Different growth pattern during microbial electrosynthesis using C. ljungdahlii evolutionary adapted on iron

Chaeho Im, Kaspar Valgepea, Oskar Modin, Yvonne Nygård, Carl Johan Franzén

This study evolved Clostridium ljungdahlii on iron to improve extracellular electron uptake, finding reduced growth on H2 and CO2 but increased acetate production on iron compared to wild-type.

Heterologous expression of pyruvate formate lyase enhances cell growth of Clostridium ljungdahlii during microbial electrosynthesis

Chaeho Im, Adolf Krige, Kaspar Valgepea, Oskar Modin, Yvonne Nygård, Carl Johan Franzén

This study enhances cell growth of Clostridium ljungdahlii during microbial electrosynthesis by heterologously expressing pyruvate formate lyase genes from Acetobacterium woodii.
